IMPROVEMENT IN PRINTING-P1138533.

Specification for'im'ng part of Letters Patent No. 110,244, datedDecember 20, 1870.

To all whom it may concern:

Be it known that I, JOHN W. KELLBERG, of the city of Philadelphia, inthe county of Philadelphia and State of Pennsylvania, have inventedcertain Improvements in Rotary Power Printing-Machines; and I do herebydeclarethe following to be a full, clear, and exact description thereof.7

My improvement in printing-presses belongs to that class of machines inwhich the paper is printed from a continuous roll or web.

in the most successful of this class of machines, that patented by thelate lamented William Bullock on the 14th of April, A. D. 18637the paperis fed to the machine from a continuous roll or web; a sheet of theproper size severed from the roll, then printed on both sides, beingcarried through the machine position andoperation of the differentparts.

Fig. 2 is an enlarged longitudinal sectional elevationof thecutting-cylinders and fly or V delivery apparatus. Fig. 3 is an end viewof the machine, showing the cuttingcylinder E, with the position of theair-pipes and openings for blowing the rear end of the sheet from thecylinder, and also the position and operation of the slitting-knife.

A is the frame of the machine, seen from one side, and having acorresponding frame upon the other side, the two sides being parallelwith each other, and supporting the several shafts and cylinders whichare placed horizontally betweenthem. C is the secondimpression-cylinder, to which is applied the power that drives themachine, and from which all the other parts of the machine derive theirmotion, its diameter being a multiple of the that impression-cylinder B,type-cylinders D D, and male cutting-cylinder F G G are theink-distributors. E is the female cuttingcylinder, audits diameter isequal to two diameters of the-malecutting-cylinder F. R P is thedelivery apparatus, for receiving each alternate sheet from the femalecutting-cylinder E and laying them in one pile. R P is the lowerdelivery apparatus, for receiving the other alternate sheets-fromthefe'malc cutting cylinder E, andlaying them also in one pile. o"! isan air-pump. b is the air-pump piston. a' is the arm operating theair-pump. 0

(shown in dotted outline in Fig. 2) is the cam which operates the armof, forcing the air through the pipes s into the pipes 8, through thepipes c c, and out .the nozzles E E E. a, a, a, a, and a are the pulleyscarrying the cords or tapes on the outside of the paper on the firstimpression-cylinder B, and between the paper and second impressioncylinder (J, and which cords or tapes carry? the forward end of thesheet of. paper from the second impression-cylinder onto the femalecutting-cylinder E,-leaving the paper at the pulley a b b, and b are thepulleys which carry the tapes or cords on the inside of the paper on thefirst impression-cylinder B, and on the outside ofthe paper on thesecond impression-cylinder G, and which cords or tapes, in combinationwith the cords or tapes on pulleys aha a a, and 0. carry the paper tothe female cutting-cylinder E at the pulley b. b is the roll or web ofpaper to be printedand cut into sheets.

When the machine is ready foroperation, or to be put in motion by theapplication of power to the second impression-cylinder (J, the forwardend of the paper, which rests'o'n the cylinder B, is inserted betweenthe two series of tapes running on the pulleys a D and, being carriedbetween the tinsttype and first "impression cylinders, receives itsfirst impression and is printedon one side, from 1 whence it is carriedbetween the two series of otgriper's, which' ware directly. opposite;each other, and so constructed, arranged, and operated as to seize theforward end of the roll immediately after its severance from thepreceding sheet; but as the rear end of the preceding sheetwould then beover the'openings' through which the gripers seizing the forward end ofthe roll, as aforesaid, must, pass, the cam which operates the arm a,attached to the air-pinup 0', forces the piston b down into the cylinder0', and drives the air out of the apertures in the cutting-cylinderE,1nade for that purpose and designated E E E, thereby removing orblowing the rear end of the cut sheet on the cylinder E out of the wayor reach of thc'gripers in seizing the forward end of the roll of paper.

The forward end of the roll'i s then seized and retained by the griperson the female cuttingcylinder Enntil it reaches the delivery apparatusLt I, when the gripers on the cylinder E are made to let go their holdof thepaper and resume their position ready for their next sheet. Thegripers on the delivery apparatus (Bullocks) then seize hold of thepaper and carry it along until after its severance from the roll anduntil just as the rear end is arrested and knocked down, when thegripers are made to release their hold and resume their position readyfor their next sheet.

The diameter of the male cutting-cylinder F. being one-fourth of that ofthe impressioncylinder C, and one-half that of the femalecntting-cylimler, the cut sheet will be one-half the circumference ofthe female cutting-cylindei E consequently eacn set or gripers on thefemale cut-ti n g-eylinder is made to operate alternately, and the camsare so arranged that one set of gripers will deliver the forward end ofthe roll to the delivery apparatus It P, and the other set of griperswill deliver the forward end of the cut sheet to the delivery apparatusR P.

It would be impossible for onedelivery apparatus of this kind to takecharge of sheets following each other in unintermitted successionwithout any space between the sheets of paper, as there would be noopportunity for the return of the knocker or fly rods from striking downthe rear end of the sheet, and for this reason a second deliveryapparatus, R P, is added, which receives and disposes of each alternatesheet, and still, if the delivery apparatus R P were to run at the samespeed as the delivery apparatus R P, the tail or rear end of the sheetdelivered to the delivery apparatu'sf R P. would be in the way of theoperation of the gripers on the delivery apparatus R P; to obviate whichdifficulty the gripers on the delivery apparatus R P are made to travelat an accelerated speed, so that as soon as they close on the forwardend of the cut sheet the sheet is slid along on thefemale'cutting-cyliuderE, leaving a space between the rear end of thecut sheet and the forward end of the roll for the operation of thegripers on the delivery apparatus R P.

It will readily be seen that the use of cords or tapes, gripers, orother device for carrying the paper can be entirely dispensed with inthe above arrangement, the paper remaining in one continuous sheet untilit reaches the cutting apparatus at the delivery end of the press. Y

When it is desired to slit the sheet of paper, a slot or rabbet is madearound the circumference of the female cutting cylinder E, into which acircular serrated blade is suspended or inserted, and being suspended atits axis on an arm, 3 the serrated blade 21 will revolve at the samespeed as the paper simply by the passage-of the paper itself, andthereby slit or perforate the paper as desired.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. In a perfecting printing-press, printing without intermission from acontinuous roll, so combining and arranging the various cylinders thatthe paper shall be in continuous contact with their convex surfacesuntil out into sheets for delivery, so as to avoid the necessity ofusing any carrying tapes, belts, gripers, or bridges, substantially asshown and set forth.

2. The roll of paper 1;", in combination and rolling contact with thefirst impression-cyliuder B, as and for the purposes substantially asdescribed.

3. An air-blast, substantially as described, for the' purpose ofremoving the rear end of the sheet from the reach of the gripers inseizing the forward end of the roll.

4. Two delivery apparatus, one running at a faster speed than the other,as and for the purposes substantially as described.

5. A circular serrated knife, for slitting or perforating the sheet,operated as and for the purposes substantially as described.
